Founded in 1996 in Lillebonne, Normandy, idéart is a human-scale architecture firm deeply rooted in its region. Since its beginnings, the agency has nurtured a strong family spirit, with a generational transition embodied by the sons of two founders—one of whom now leads the firm.
Active with local authorities, businesses, and private clients, idéart designs tailor-made projects that combine sustainability, functionality, and aesthetics: rehabilitation of public facilities, short-supply-chain constructions, professional spaces, extensions, and renovations.
Committed to values of proximity, responsiveness, and transparency, the agency places listening and dialogue at the heart of its approach.
Driven by the desire to adopt responsible practices, Idéart is engaged in a CSR initiative and is preparing for the Lucie label certification, aiming to further strengthen its positive impact on the region, the environment, and human relationships.
